For the best results, you will want to spray these down with a scrubbing cleaner like scrubbing bubbles and let them sit while you work on the next task. When you come back these should be easier enough to clean.
After you have given your entire bathroom a good scrubbing and you have a fresh slate to work with you can then start to put everything back into your bathroom. While putting everything away, take the time to declutter.
Consider adding some new things to your bathroom like organizers, added shelving for storage, and decor that helps to give your bathroom a luxurious feel that helps to melt away your stress at the end of the day.
